A recent study by the Mayo Clinic found that the ability to stand on one leg is a strong indicator of overall health, particularly as we age. Researchers discovered that balance declines more rapidly with age than walking gait or grip and knee strength. This decline can lead to unintentional falls, a significant risk for older adults. The good news is that balance exercises can help maintain coordination and reduce the risk of falls.
